General
The PIM-430 is a detection module that interfaces between a main control panel detection circuit(s) or addressable node(s)
and Protectowire Linear Heat Detector. The module may be configured to provide two (2) Class B (Style B) alarm initiating
circuits each capable of operating up to 2,000m (6,560 ft.) of Protectowire Linear Heat Detector or one (1) 3-wire Class B
(Style B) dual input initiating circuit capable of operating up to 2,000m (6,560 ft.) of Protectowire Type TRI (TRI-WireTM).
The PIM-430 initiating circuits are also compatible with other types of normally open non-resistive contact devices.
Description
The PIM-430 Dual Input Interface Module is designed for easy mounting and includes a convenient “snap-lock” mounting
track that enables the module to be conveniently installed inside a host control panel or in any enclosure meeting the environmental requirements of the application. The module is also available from the factory mounted in a NEMA-4X (IP66) rated
enclosure (Option E) that can be mounted outside of the host panel in a remote location.
In order to ensure proper operation, each PIM-430 Interface Module requires regulated 24 VDC external power which is normally provided by the host control panel. Each module contains a Green “Power On” LED indicator to provide visual confirmation that the module is powered. One (1) set of Form C alarm contacts, and one (1) set of Form C trouble contacts are
provided for each detection zone, and are used to interface the unit to a corresponding detection zone(s) in the host fire alarm
panel. The module’s alarm initiating circuits are non-latching and self restore upon clearing the cause of the alarm state. The
host panel’s zone detection circuits are used to retain the alarm latch (memory) until manually reset.
An ISO 9001 Registered Company
The metered version of the Interface Module, Model PIM-430D,
contains an on-board alarm point location meter that is manually
activated by means of a toggle switch. The high intensity LCD
meter will display the distance in meters from the start of the detector portion of the zone in alarm to the heat actuated point on the
Protectowire Linear Heat Detector. When the module is used with
standard 2-wire Protectowire, moving the switch to the left ()
position will activate the alarm reading for zone one (1), while moving the switch to the right (), displays the alarm reading for zone
two (2). When TRI-WireTM is utilized, the module is configured as
a single zone and the switch must be moved to the left position to
obtain the location reading of the heat actuated pre-alarm point on
the TRI-WireTM Dual Temperature Linear Heat Detector. High temperature alarm (200° F/93° C) distances are not displayed.
When detection in hazardous areas is required, each PIM-430 Interface Module can be provided with two (2) shunt diode barriers
(Option I). This option provides two (2) intrinsically safe Class B
(Style B) detection circuits for use with standard 2-wire Protectowire. The maximum length of Protectowire that can be connected
to each circuit is 1,829m (6,000 ft.). When Option I is utilized with
TRI-WireTM, the module will accommodate one (1) TRI-WireTM
zone with a maximum length of 1,829m (6,000 ft.).
The shunt diode barriers limit the voltage and current in the detection circuits to values that are incapable of causing an explosion. In a
standard 2-wire configuration, each intrinsically safe circuit is rated
for use in areas that are classified as Class I, II, and III, Division 1,
Groups A, B, C, D, E, F, and G. When TRI-WireTM is connected to
the module, the intrinsically safe circuit may only be used in areas
classified as Class I, II, and III, Division 1, Groups C, D, E, F, and
G. Refer to Protectowire Control Drawing IL-1613.
Only Protectowire Linear Heat Detectors and/or a non-energy storing contact initiating device may be used on PIM-430 intrinsically
safe detection circuits. The intrinsic safety barrier compatible for use
with the PIM-430 Series is Part Number 9001/01-280-100-101 as
manufactured by R. Stahl Inc. Two (2) Stahl Intrinsic Safety Barriers
per module are required. Consult the Factory for specific information on hazardous location installations as additional limitations
may apply.

PIM-430 Commissioning Procedure
Caution: All auxiliary alarm devices and outputs controlled
by the Host Fire Alarm Panel should be disconnected prior to
connecting any PIM-430 Interface Modules to the system. To
ensure compatibility, the host panel’s initiating device circuits must
accept normally open alarm shorting and normally closed trouble opening devices.
1. Remove factory supplied 4.7K 1/2w end-of-line resistors (ELR)
from terminal TB2 and install across the conductors at the end
of each Protectowire run as shown on the wiring diagram. In
Protectowire 2-wire applications, if one of the detection zones is
unused, a 4.7K end-of-line resistor must be installed across the
unused zone terminals on terminal block TB2.
2. Connect Protectowire Linear Heat Detector to the module using
terminal block TB2. Refer to wiring diagram for specific zone
or TRI-WireTM pre-alarm and high temperature circuit terminal
designations. Important: To ensure proper TRI-WireTM operation, the
polarity of the circuit must be maintained as illustrated.
3. Connect host panel’s initiating circuit end-of-line device across
terminals 2 & 6 on terminal block TB3 and 1 & 5 on TB4 as
required by the application. See host panel wiring specifications.
If polarity is required, connect (+) to terminal 2, (-) to terminal 6
on TB3 and (+) to terminal 5, and (-) to terminal 1 on TB4.
4. Connect host panel’s initiating device circuit(s) across terminals 2
(+) & 3 (-) on terminal block TB3 and/or terminals 4 (-) & 5 (+)
on TB4 as functionally required by the application. Install
jumpers between terminals 3 & 4 on TB3 and TB4. See host
panel wiring specification, and observe polarity if necessary. The
host panel’s initiating device circuits must accept normally open
alarm shorting and normally closed trouble opening devices.
5. Connect a regulated 24 VDC switched power source across input
terminals 4 (+) & 5 (-) on terminal block TB1. Turn on power.
Only the green “Power” LED should be on, and the host panel
initiating device circuit(s) trouble indication should clear. When
code or local authority requires grounding, connect terminal 6
marked E-GND on TB1 to earth ground.
6. At the end of the Protectowire Linear Heat Detection run, open
the circuit at the 4.7K end-of-line resistor. The yellow “Trouble”
LED on the PIM-430 will light, and the host panel should report
a trouble condition. Reconnect the end-of-line resistor and the
“Trouble” LED will extinguish and the host panel should reset to
normal. Perform this test for each active Protectowire zone or the
pre-alarm and high temperature alarm legs of the TRI-WireTM
detection circuit. Note: Manual trouble reset of the host panel
may also be required depending upon the make and model
installed.
7. At the end of the Protectowire Linear Heat Detection run, short
the circuit across the 4.7K end-of-line resistor. The red “Alarm”
LED on the PIM-430 will light and the host panel should report
an alarm condition. To restore the system to normal, reset the
host control panel. The PIM-430 Protectowire alarm initiating
circuit(s) are non-latching and self-restore upon clearing the short
from the circuit(s). Perform this test for each active Protectowire
zone or the pre-alarm and high temperature alarm legs of the
TRI-WireTM detection circuit.
Alarm Point Location Meter Calibration
("D" Models)
After installation, the meter must be calibrated to compensate for
the resistance of the copper feed wire between the PIM-430D
Interface Module and the start of the Protectowire portion of the
circuit. Adjust the meter per the following procedure:
1. Disconnect all alarm and/or releasing devices from the host
system before applying power to the module.
2. Connect a jumper across the Zone 1 detection circuit in the
first zone box at the beginning of the Protectowire run. For
TRI-WireTM installations, jumper across the low temperature
pre-alarm portion of the detection circuit (pink and black
conductors). Caution: This action will cause an alarm condition
on the detection circuit.
3. On the Interface Module, move and hold the meter read toggle
switch to the left () position. The meter will display the
copper feed cable error for Zone 1.
4. To cancel out (zero) this value, adjust the “Z1 Zero”
potentiometer on the Interface Module using a small screwdriver to turn the adjustment screw until the meter reads zero.
Remove the jumper from the detection circuit, and reset the
host control panel. For TRI-WireTM applications go to Step 6.
5. This step pertains only to 2-wire Protectowire installations
where Zone 2 is utilized. Connect a jumper across the Zone 2
detection circuit. This action will cause an alarm condition.
Move and hold the meter read toggle switch to the right ()
position. The meter will display the copper feed cable error.
Repeat Step 4 to cancel out (zero) this value using the “Z2 Zero”
potentiometer. Remove the jumper from the detection circuit
and reset the host panel.
6. Although preset at the Factory, a calibration adjustment may be
needed to compensate for installation temperature variations.
To calibrate the meter, after the offset adjustment (Item 4),
place a short across the end of the Protectowire run at the endof-line resistor zone box on the Zone 1/TRI-WireTM Pre-alarm
circuit. In TRI-WireTM applications, the pre-alarm function is
identified by the pink and black conductors. Caution: This
action will cause an alarm condition on the detection circuit.
Move and hold the meter read switch to the left () position
and adjust the “Calibrate” potentiometer until the display
shows the actual length of the linear detection cable installed
on the circuit. Remove the short from the circuit and reset the
host panel. No further calibration adjustments are required for
this module.
7. Repeat this procedure for all other metered PIM-430 Interface
Modules in the system. Reconnect all auxiliary devices disconnected from the Host Fire Alarm Panel in Step 1. Return
system to normal operation.
